The video tutorial covers alternating series, focusing on how to test them for convergence or divergence using the alternating series test. It explains the conditions under which a series converges and provides examples, including the alternating harmonic series. The tutorial also demonstrates how to express series in sigma notation and apply derivatives to analyze series behavior. When the alternating series test fails, the video shows how to use the test for divergence.
